AI agents call readDistance to retrieve information from Chotu Robo Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'read' prefix and 'Distance' suffix indicate this tool retrieves sensor readings without modifying state or executing arbitrary operations. It is consistent with the server's sensor integration capabilities. Distance sensor readings are non-destructive queries of hardware state.
From the tool's definition Tool name 'readDistance' indicates reading sensor data from a distance sensor (likely ultrasonic or infrared). No description provided, but the name and server context (Arduino-based robotics with sensors) strongly suggest passive data retrieval from hardware.
Documented attack patterns abuse exactly the kind of access readDistance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Chotu Robo Server, and nothing reaches the server without passing your rules. This is the rule we recommend for readDistance:
{
"version": "1",
"default": "deny",
"tools": {
"readDistance": {}
}
}readDistance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

readDistance. It is categorised as a Read tool in the Chotu Robo Server MCP Server, which means it retrieves data without modifying state.
Register the Chotu Robo Server MCP server in PolicyLayer and add a rule for readDistance: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Chotu Robo Server. Nothing to install.
readDistance is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the readDistance rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for readDistance. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
readDistance is provided by the Chotu Robo Server MCP server (vishalmysore/choturobo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
